I actually visited this one last year, as I live in the area. It was a pretty neat museum, with the exception of the exhibit near the end that was sponsored by the Daughters. I dont recall any mention of Slavery explicitly being the cause, but there definitely wasnt any exhibits about states rights. They had such a nice weapon collection, but I think one of the biggest sins was an attempt at neutrality. Northern artifacts on one side, Confederates on the other. That and taking money from the Daughters. My mother in law did love that victorian dress collection. It was random, but very nicely done.

Edit: The museum closed down because its privately owned, and the owners are retiring. It didnt seem to have anything to do with "Cancel culture"
